I'm unsure if that comment was straight or sarcastic. I hadn't considered the RV-10 in my comments. Yes, you'll pull 175 easy enough, but it's at a cost of feeding an IO-540. 160/65 is more the go. And yes, I've flown and instructed in them too.
Firstly, consider the unknowns of the amateur build. For anyone seriously considering an RV purchase ex the US, with the intent of aeros - just ask yourself whether you want to be stressing an airframe about which you know bugga all. At least the local builds have been under some scrutiny, and are probably closely built to VANS' plans.
Then we come to just what your RV has been doing in the US. Some years back there was an RV8 accident in Oregon,(?), where the airframe did fail, and as far as I know, it was due to some quite non-recommended aeros....way outside the aircrafts' envelope. You would really want to know just how many hours your US import had done in the hands of a DYO aerobating cowboy. Maybe you wouldn't!
Try to look past the panel chocka with EFIS and u beaut IFR avionics. It's the airframe build that's important.
Maybe you'd be better off doing your aeros in a local school aircraft, (Decathalon, Pitts,Tiger), which is designed for the job - and get yourself a nice 'cruising' RV which has no aeros history?
happy days,
